How to Use the Weight Converter
Enter a weight value and select its current unit — the converter instantly shows the equivalent value in kilograms, pounds, ounces, and stone, applying the exact conversion factors automatically without needing to route manually through an intermediate unit.
The Weight Converter handles all four common units directly — here's what to enter.
Entering a value and unit
Enter a weight and select its current unit — the tool converts it instantly to the other three units, including the stone-and-pounds combined format common in UK contexts, if supported.
Converting a combined stone-and-pounds figure
For a weight given as "X stone Y pounds," check whether the tool accepts that combined format directly — if not, converting the stone portion to pounds first (multiplying by 14) and adding the remaining pounds gives a single figure to enter.
